My Passport Ultra 2TB isn't mounting in MAC

I don’t want to “repair” until I understand if this means I can get my data off this drive. Any help would be greatly appreciated! I have a MyCloud and I should’ve been backing up more regularly but I travel a lot for work and have been racking up a ton of data without being able to back up on my other external drive which is in my Office. {MyCloud}. This drive was really pricey and I’m shocked it failed so easily. HELP!
